but remember that they all offer slightly different stuff for both platforms, not just Mac.
Tried TaxAct once but never again. Couldn't even import from the previous year.
Never tried H&R Block
TurboTax, TaxAct, and H&R Block are the big ones, and they all differ in what they offer for use with Macs (e.g., online vs. CD versions).
Would like to hear of your experiences (the good, the bad, and the ugly!) with any of them, and your recommendations.
